Five health standards for modern homes
Since all factors of the indoor environment will act on the human body, and through the residential development, there are more and more high-rise buildings, and people are paying more and more attention to residential indoor hygiene.
To this end, experts put forward the following sanitary standards for modern residences from five aspects: sunshine, daylighting, indoor height, microclimate and air clarity:1.
Sunlight can kill microorganisms in the air and improve the body’s immunity.
Experts believe that in order to maintain human health and normal development, the daily sunshine time must be more than 2 hours per day.
Refers to the natural light that can be obtained in the house. The ratio of the effective area of the window to the floor area of the room should be greater than 1:15.
The indoor net height must not be less than 2.
This standard is stipulated in the “Certificate of Civil Building Design”.
For the occupants, the appropriate net height gives a good sense of space, and the net height is too low to reduce people’s depression.
Experiments have shown that when the room height is lower than 2.
At 55 meters, the indoor carbon dioxide concentration is high, which has a significant impact on indoor air quality.
Microclimate: In order to maintain good sanitation, it is generally required that the room temperature should be no less than 12 seconds in winter, no more than 30 °C in summer, and the relative humidity in the room should be no more than 65%.
15 m / s, winter is not greater than 0.
3 m / s.
It refers to the total amount of harmful gases, metabolites, dust and bacteria in the air inside the living room. The harmful gases are mainly carbon dioxide, sulfur dioxide, helium, formaldehyde, toluene and so on.
In addition to the above five basic standards, indoor hygiene standards also include lighting, isolation, moisture, radiation and other requirements.
